 - Remove filename after inline in Content-Disposition header according to RFC2183
 - Depends on `mathieucarbou/Async TCP @ ^3.1.4`
 - Arduino 3 / ESP-IDF 5.1 compatibility
+- Added all flavors of `binary()`, `text()`, `binaryAll()` and `textAll()` in `AsyncWebSocket`
+- Added `setCloseClientOnQueueFull(bool)` which can be set on a client to either close the connection or discard messages but not close the connection when the queue is full
